解决方案：.

tsconfig.json文件夹加上

{"compilerOptions": {"target": "ES2020","useDefineForClassFields": true,"module": "ESNext","lib": ["ES2020", "DOM", "DOM.Iterable"],"skipLibCheck": true,/* Bundler mode */"moduleResolution": "bundler","allowImportingTsExtensions": true,"resolveJsonModule": true,"isolatedModules": true,"noEmit": true,"jsx": "preserve",/* Linting */"strict": true,"noUnusedLocals": true,"noUnusedParameters": true,"noFallthroughCasesInSwitch": true},"include": ["src/**/*.js","src/**/*.ts","src/**/*.tsx","src/**/*.vue","./auto-imports.d.ts"],"references": [{ "path": "./tsconfig.node.json" }]
}

"./auto-imports.d.ts"即可

vite-env.d.ts文件夹粘贴

/// <reference types="vite/client" />
declare module '*.vue' {import { ComponentOptions } from 'vue'const componentOptions: ComponentOptionsexport default componentOptions
}
